What Is a Packing List?

A packing list is a document that itemises every package in a shipment, listing the contents, quantity, weight, and dimensions of each box or pallet. Unlike the commercial invoice (which shows values and prices), the packing list is purely logistical — it tells customs officers, carriers, and recipients exactly what is inside each package and how it is packed. While not always legally required for every shipment, a packing list is strongly recommended for all international parcels and essential for multi-piece shipments, sea freight, and air freight. Discrepancies between the commercial invoice and packing list are one of the most common causes of customs delays.

Key Fields on a Packing List

Shipment Reference

Your invoice number or order reference that links the packing list to the commercial invoice. Must match exactly.

Package Number

Each box or pallet is numbered (e.g. 1 of 5, 2 of 5). Every label on every package should reference this number.

Contents Description

The specific contents of each individual package. More detailed than the commercial invoice — include product names, model numbers, colours, or sizes.

Quantity per Package

The number of units inside each specific box. Totals across all packages must match the commercial invoice.

Net Weight

The weight of goods only (excluding packaging) for each package and in total.

Gross Weight

The total weight including packaging for each package. Carriers and customs both use gross weight.

Dimensions

Length × Width × Height in cm for each package. Required for volumetric weight calculation and container planning.

Total Packages & Weight

A summary row at the bottom totalling number of packages, total net weight, total gross weight, and total volume (CBM).

Marks & Numbers

Any shipping marks, special handling symbols, or customer reference codes printed on the packages — e.g. 'Handle with care', 'This side up', or buyer PO numbers.

How to Prepare a Packing List

1

List Every Package Separately

Create one row for each box, carton, or pallet. If five boxes have identical contents, you can group them on one row — but note the quantity of boxes in that row.

2

Describe Contents Specifically

Use the same product descriptions as the commercial invoice. Add extra detail where helpful — model numbers, batch codes, or colours. Avoid generic terms like 'goods' or 'merchandise'.

3

Weigh and Measure Each Package

Record the gross weight (with packaging) of each package in kg. Measure length, width, and height in cm. This information is used by carriers for freight charges.

4

Cross-Check Against the Commercial Invoice

Verify that total quantities and descriptions match the commercial invoice. Any discrepancy will be flagged by customs and cause delays.

5

Attach to Each Package

Print the packing list and attach it to the outside of each package in a clear document wallet. Include the invoice number on each label so it can be matched.

Common Mistakes to Avoid

⚠️

Packing List Doesn't Match Invoice

If the packing list shows 10 units but the commercial invoice shows 12, customs will hold the shipment for investigation. Always cross-check totals before printing.

⚠️

Including Prices on Packing List

A packing list should NOT include item prices or total values — those belong on the commercial invoice. Mixing them up creates confusion for customs and carriers.

⚠️

Missing Package Dimensions

Without dimensions, carriers cannot calculate volumetric weight accurately, leading to invoice adjustments after collection. Always include L×W×H for each package.

⚠️

Single Packing List for Multi-Piece Shipment

For a multi-piece shipment, attach a copy of the packing list to every package, not just the first one. If packages get separated, each one needs its own documentation.

Frequently Asked Questions

Is a packing list required by law for international shipments?

▾

A packing list is not always legally mandatory, but customs authorities in most countries require it for commercial shipments. For sea freight, most shipping lines require it. For air freight, it is standard practice. For parcels, while couriers may not always require it, including one significantly reduces the risk of customs delays.

What is the difference between a packing list and a commercial invoice?

▾

A commercial invoice shows the financial transaction — what was sold, at what price, and by whom. A packing list shows the physical contents — what is in each box, how many units, what it weighs and measures. Both are needed for customs, but only the commercial invoice is used to calculate duties and taxes.

Does every box in a multi-piece shipment need a packing list?

▾

Yes. Attach a packing list to every package in a multi-piece shipment. If boxes are separated during transit, each one must have its own documentation to pass through customs independently.

Can I combine the packing list and commercial invoice into one document?

▾

Yes, for simple shipments. A combined packing list / commercial invoice includes all the fields from both documents. However, for complex shipments with many SKUs or consignments involving letters of credit, keep them as separate documents.

What happens if the packing list and commercial invoice don't match?

▾

Customs will hold the shipment until the discrepancy is explained. You may need to provide a revised document or a letter of explanation. This can add days or weeks to transit time and incur storage fees.
